Change description:
The syntax for enabling multiple features in a frame using feature policy has changed from allow="feature1 feature2 feature3" to allow="feature1; feature2; feature3". This is to support listing origins for each feature. The old syntax is currently handled through a special case in the parser, but that code should be removed.
Changes to API surface:
- Remove support for "feature1 feature2 feature3" syntax in <iframe allow>.
